A ueaumima mamasi.7-, 1319,;Seria1 no. saaeae Be it known" that WILLIAM L. CALmvn n, a citizen of the United Statesyresiding at Canton, in the county of Stark and State of i Ohio, have invented anew and useful lyletaL is used for conveying Water for irrigation power or simllar purposes the metal trough I being formed of successive StEGHODSDf proper curvature and oined together to form a'continuous channel. To facilitate erection of :tlumes of this, character,- thejoints between the several sections "should be -made Without rivetsjor bolts and to p'rovide a Water tight jointhetWee-n the several sections means should v beiprovlded forclai nping the overslapped ends of the sections tightly together; a The joints. should further add a certain,

amount of circumferential,stiffness to the thin shell of the flame sections and should jb QfmadQ/ Water tight Without l the rmor isolder orlthe'like, i

A practical embodiment of the invention is disclosed in the accompanying drawings. forminga part of this specification in which similar numerals of referenceindicate corresponding parts throughout the several It is frequently necessary to construct flumes of considerable length and to support the sections going to make up the flumeaat a considerable distance above the ground.

Where it is necessary to conduct ater across valleys or depressions and maintain the proper level or inclination ofthe fluine so that the watenmay, if necessary be carried over intervening elevations, it'often becomes necessary to construct a trestle Work or frame Work which at some points extends. to a considerable height While at other-points the trestle or frame Work may be comparatively low, the flume being supported throughout its entire length-by suitable hangers 1 which" are ,carried by thertrestle or frame Work.

The flume sections 2 or 2? and? are sheet metal of semicircular cross section as illustrated in 'the drawings, Referring to the construction illustrated in Fig. 3 thefiume sections? and Q alternate throughoutthe lengthrof the flume. These sections are of course of suitable length topermitof their. being easily handled andassembled. 1 Eachof the sections "2 shOWninFigB is provided ateach endwithi an integral reinforcement or pressurefportion3 formed by foldingthe ,end 1 of the section back upon itself.
